Molex 0702465021 Equivalent & Substitute Parts

Part Overview

The Molex 0702465021 is a shrouded rectangular connector header with 50 positions arranged in 2 rows at 0.100" (2.54mm) pitch, designed for through-hole mounting with solder termination. This connector is classified as obsolete, which necessitates identification of active equivalent and substitute parts that maintain functional compatibility for board-to-cable/wire applications. The part features gold-plated mating contacts, tin-lead plated posts, and phosphor bronze contact material with UL94 V-0 flammability rating.

Engineering Selection Recommendations

All listed substitute parts maintain functional equivalence to the Molex 0702465021 through identical connector geometry, pitch, row configuration, and push-pull fastening mechanism. Selection among substitutes should be based on the following criteria:

For RoHS3 Compliance Requirements: TE Connectivity 1-5103308-0 and 1-5103309-0, 3M 30350-6002HB, and 3M N2550-6003-RB are ROHS3 compliant. These parts are suitable for applications requiring modern environmental compliance standards.

For Active Product Status with Established Supply: TE Connectivity 1-5103308-0 maintains the highest inventory availability (6300 pcs) among RoHS3-compliant options. TE Connectivity 1-103308-0 and 1-103309-0 are active parts with established supply chains, though classified as RoHS non-compliant.

For Contact Material Equivalence: Amphenol ICC (FCI) 66506-031LF and 66506-032LF maintain phosphor bronze contact material identical to the original Molex part, with RoHS compliance and active product status. These parts differ in contact post length (0.105" vs. 0.150").

For Operating Temperature Range: TE Connectivity parts specify -65°C to 105°C operating range. 3M 30350-6002HB specifies -55°C to 105°C. Hirose HIF3FCA-50PA-2.54DSA(71) specifies -55°C to 85°C, which is narrower than other options.

For Packaging Considerations: TE Connectivity parts are supplied in tubes. 3M 30350-6002HB is supplied in trays. Amphenol ICC (FCI) parts are supplied in trays. Hirose and 3M N2550-6003-RB are supplied in bulk. Packaging selection depends on assembly process requirements.

Frequently Asked Questions (FAQ)

Q: Can TE Connectivity 1-5103308-0 directly replace the Molex 0702465021?

A: Yes. Both parts share identical connector type, contact configuration, pitch, row spacing, shrouding, mounting method, and fastening mechanism. The TE part is active with RoHS3 compliance and higher inventory availability.

Q: What is the difference between TE Connectivity 1-103309-0 and 1-5103309-0?

A: Both parts are functionally equivalent with identical electrical and mechanical specifications. The primary difference is RoHS status: 1-103309-0 is RoHS non-compliant, while 1-5103309-0 is ROHS3 compliant. Contact finish thickness on the mating surface also differs (30.0µin vs. 15.0µin).

Q: Are Amphenol ICC (FCI) 66506-031LF and 66506-032LF interchangeable?

A: Both parts are mechanically and electrically equivalent with identical pitch, row configuration, and shrouding. The difference is contact post length: 66506-031LF has 0.105" posts, while 66506-032LF has 0.150" posts. Selection depends on PCB thickness and assembly requirements.

Q: Does the 3M N2550-6003-RB offer higher current capacity than the original Molex part?

A: The 3M N2550-6003-RB is rated for 1.75A per contact, while the Molex 0702465021 does not specify a current rating. The 3M part provides higher current handling capability for applications requiring increased power delivery.

Q: What packaging format is best for high-volume assembly?

A: Tube packaging (TE Connectivity parts) is standard for automated pick-and-place assembly. Tray packaging (3M 30350-6002HB, Amphenol ICC parts) is suitable for semi-automated processes. Bulk packaging (Hirose, 3M N2550-6003-RB) requires manual handling and is typically used for lower-volume applications.

Q: Is the Hirose HIF3FCA-50PA-2.54DSA(71) suitable for high-temperature applications?

A: The Hirose part specifies -55°C to 85°C operating range, which is narrower than most alternatives. For applications requiring -65°C to 105°C operation, TE Connectivity or 3M N2550-6003-RB are more appropriate selections.

Q: What is the significance of contact finish thickness differences?

A: Contact finish thickness affects durability and wear resistance. TE Connectivity 1-103309-0 specifies 30.0µin mating finish thickness, while 1-5103308-0 specifies 15.0µin. Thicker finishes provide longer service life in high-cycle mating applications.
