TE Connectivity 1761605-7 Equivalent & Substitute Parts

Part Overview

The TE Connectivity 1761605-7 is a rectangular connector header, right-angle mounted, with 20 positions at 2.54mm pitch. This through-hole component features shrouded 4-wall construction with male pins, solder termination, and push-pull fastening. The part operates across -65°C to 105°C with a 250VAC rating and 1A per contact current capacity.

The 1761605-7 carries an obsolete product status. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements. Active alternatives with identical or compatible electrical and mechanical parameters are available from TE Connectivity and other manufacturers.

Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 2-1761605-7

The 2-1761605-7 is the direct equivalent to the obsolete 1761605-7. Both parts share identical electrical and mechanical specifications, including pitch, position count, mounting orientation, shrouding, and contact materials. The 2-1761605-7 carries active product status and ROHS3 compliance, ensuring long-term supply availability and regulatory alignment. This part is available in bulk packaging with 4,791 units in stock. The only difference is insulation color (blue versus black), which does not affect electrical performance or mechanical compatibility.

Secondary Recommendation: TE Connectivity 5103311-5

The 5103311-5 maintains compatibility across all critical parameters: 20-position, 2-row, 2.54mm pitch, right-angle through-hole mounting, shrouded 4-wall construction, and solder termination. Contact material is brass rather than phosphor bronze, and contact length post is 0.135" versus 0.102", accommodating deeper PCB stack-ups. This part is active, ROHS3 compliant, and available in tube packaging with 9,485 units in stock.

Tertiary Recommendations: Molex 0702472052 and 0702472054

Both Molex C-Grid 70247 series parts (0702472052 and 0702472054) meet all critical substitution criteria. These parts feature phosphor bronze contacts with gold mating finish, identical pitch and position configuration, and right-angle through-hole mounting. Contact length post is 0.120", suitable for standard PCB applications. Both are active, ROHS3 compliant, and available in bulk (1,126 units) and tray (6,766 units) packaging respectively. Operating temperature specifications are not provided but do not preclude substitution.

HARTING SEK Series Options: 09185205323, 09185206321, 09185207323

HARTING parts 09185205323, 09185206321, and 09185207323 provide right-angle, 20-position, 2.54mm pitch alternatives with copper alloy contacts and gold mating finish. These parts feature latch holder fastening (versus push-pull) and extended operating temperature range (-55°C to 125°C). Contact length post varies (0.114" to 0.177"), allowing selection based on PCB requirements. All three are active, ROHS3 compliant, and available in bulk packaging. The 09185205323 and 09185207323 are functionally equivalent; 09185206321 offers extended post length for deeper stack-ups.

Compliance and Supply Considerations

All recommended substitutes carry ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Moisture sensitivity level remains 1 (unlimited) across all options, eliminating special handling requirements. All parts are classified under ECCN EAR99 and HTSUS 8536.69.4040, maintaining consistent export and tariff treatment.

Frequently Asked Questions (FAQ)

Q: Can the 2-1761605-7 directly replace the obsolete 1761605-7 in existing designs?

A: Yes. The 2-1761605-7 is electrically and mechanically identical to the 1761605-7. All critical parameters—pitch, position count, mounting type, shrouding, contact materials, and electrical ratings—are equivalent. The only difference is insulation color (blue versus black), which does not affect performance or compatibility.

Q: What is the difference between push-pull and latch holder fastening types?

A: Push-pull fastening uses a simple push-to-mate, pull-to-disconnect mechanism. Latch holder fastening uses mechanical latches or hooks for positive engagement. Both provide secure mating and are functionally compatible for the 1761605-7 application. Selection depends on user preference for mating force and disconnect method.

Q: Are HARTING parts with latch holder fastening compatible with TE Connectivity push-pull mated connectors?

A: Fastening type refers to the connector header design, not the mated connector. Compatibility is determined by pitch, position count, contact type, and shrouding—all of which are identical across TE Connectivity and HARTING options. Mated connectors must match the specific fastening type of the header selected.

Q: Does contact length post variation affect PCB compatibility?

A: Contact length post determines how far the solder tail extends below the PCB surface. Variations from 0.102" to 0.177" accommodate different PCB thicknesses and stack-up configurations. Selection should match the specific PCB design. Shorter posts (0.102" to 0.120") suit standard single-layer or thin multi-layer boards; longer posts (0.135" to 0.177") accommodate thicker assemblies.

Q: What is the significance of contact material differences (phosphor bronze versus brass versus copper alloy)?

A: All three materials—phosphor bronze, brass, and copper alloy—provide adequate electrical conductivity and mechanical strength for this application. Phosphor bronze offers superior spring characteristics; brass provides cost efficiency; copper alloy balances performance and cost. All are compatible with gold mating finish and meet the 1A per contact current rating.

Q: Are Molex parts fully compatible with TE Connectivity designs?

A: Molex 0702472052 and 0702472054 are mechanically and electrically compatible with the 1761605-7 across all critical parameters: pitch, position count, mounting type, shrouding, contact finish, and flammability rating. Mated connectors must be selected to match the Molex header design. Cross-manufacturer mating is not supported.

Q: What packaging options are available, and do they affect electrical performance?

A: Substitute parts are available in bulk, tube, and tray packaging formats. Packaging affects handling, storage, and logistics but does not alter electrical or mechanical performance. Selection should be based on production volume and inventory management requirements.

Q: Do all substitute parts meet the original 250VAC voltage rating?

A: The 1761605-7 specifies 250VAC. TE Connectivity 2-1761605-7 and 5103311-5 maintain this rating. Molex and HARTING parts do not provide voltage ratings in the available data. For applications requiring explicit 250VAC compliance, TE Connectivity options are recommended.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All recommended substitute parts carry ROHS3 compliance certification. The original 1761605-7 is marked "not applicable" for RoHS status due to its obsolete designation. Active alternatives ensure compliance with current environmental and regulatory standards.

Q: Can the 09185206324001 or 09185206904001 (vertical mounting) be used as substitutes?

A: No. These HARTING parts feature vertical through-hole mounting without right-angle orientation. They are not compatible with applications requiring right-angle board-to-cable connections. Only right-angle variants (09185205323, 09185206321, 09185207323) are suitable substitutes for the 1761605-7.
