Engineering Selection Recommendations

TE Connectivity 3-1761603-1 (Primary Substitute)

The 3-1761603-1 is the direct active equivalent within the TE Connectivity AMP-Latch series. This part maintains identical electrical and mechanical specifications to the 1-1761602-1, including contact length, insulation height, and operating temperature range. The 3-1761603-1 carries ROHS3 compliance status and is available in bulk packaging. The contact finish thickness on mating surfaces is increased to 30.0µin (0.76µm) compared to the original 15.0µin, providing enhanced durability. This part is recommended as the primary replacement for direct substitution in new designs and production continuity.

TE Connectivity 5103308-7 (Secondary Substitute)

The 5103308-7 maintains core electrical and mechanical compatibility with identical pitch, row spacing, and connector configuration. This part features extended contact post length (0.120" vs. 0.102") and increased insulation height (0.388" vs. 0.350"), resulting in a taller overall profile. Contact material is brass rather than phosphor bronze. ROHS3 compliance and REACH unaffected status are confirmed. This part is suitable for applications where the increased post length and insulation height do not conflict with board layout constraints.

Assmann WSW AWHW 34G-0202-T (Alternative Substitute)

The AWHW 34G-0202-T from Assmann WSW Components provides cross-manufacturer compatibility with identical pitch and connector configuration. This part features a higher current rating (3A per contact vs. 1A), making it suitable for higher-power applications. The operating temperature range is narrower (-40°C to 105°C vs. -65°C to 105°C). Contact post length is extended to 0.130" (3.30mm), and insulation material includes glass-filled PBT. ROHS3 compliance and REACH unaffected status are confirmed. This part is appropriate for applications requiring higher current capacity and cross-manufacturer sourcing flexibility.

Frequently Asked Questions (FAQ)

Q: Can the 3-1761603-1 be used as a direct replacement for the 1-1761602-1?

A: Yes. The 3-1761603-1 is electrically and mechanically equivalent to the 1-1761602-1. Both parts share identical pitch (0.100"), row spacing (0.100"), contact length specifications, insulation height, and operating temperature range (-65°C to 105°C). The primary difference is product status: the 3-1761603-1 is active and ROHS3 compliant, while the 1-1761602-1 is obsolete.

Q: What are the key differences between the TE Connectivity substitutes and the Assmann WSW part?

A: The Assmann WSW AWHW 34G-0202-T differs in three areas: (1) current rating is 3A per contact versus 1A for TE parts, (2) operating temperature minimum is -40°C versus -65°C for TE parts, and (3) contact post length is 0.130" versus 0.102" for the original part. All other critical parameters including pitch, row spacing, connector type, and shrouding configuration are identical.

Q: Does packaging format affect electrical or mechanical compatibility?

A: No. The 1-1761602-1 is supplied in standard packaging, the 3-1761603-1 in bulk, and the 5103308-7 in tray format. Packaging format does not affect connector performance, electrical characteristics, or mechanical fit. Selection should be based on procurement and inventory requirements.

Q: Are there temperature range limitations when substituting parts?

A: The 1-1761602-1 and TE Connectivity substitutes (3-1761603-1 and 5103308-7) operate across -65°C to 105°C. The Assmann WSW AWHW 34G-0202-T operates across -40°C to 105°C. If the application requires operation below -40°C, the Assmann part is not suitable. For applications within -40°C to 105°C, all four parts are compatible.

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

A: The 1-1761602-1 has 15.0µin (0.38µm) gold plating on mating contacts, while the 3-1761603-1 has 30.0µin (0.76µm). Increased plating thickness provides enhanced wear resistance and contact durability over extended mating cycles. The 5103308-7 maintains 15.0µin thickness. All parts meet UL94 V-0 flammability requirements.

Q: Can the 5103308-7 be used in applications with tight PCB spacing?

A: The 5103308-7 has an insulation height of 0.388" (9.86mm) compared to 0.350" (8.89mm) for the original part. This 0.038" (0.97mm) increase may affect board layout compatibility. Verify PCB clearance and component spacing before substitution.

Q: What compliance certifications apply to each substitute part?

A: The 1-1761602-1 has RoHS status listed as not applicable. The 3-1761603-1, 5103308-7, and AWHW 34G-0202-T are all ROHS3 compliant. The 5103308-7 and AWHW 34G-0202-T carry REACH unaffected status. All parts are classified as EAR99 for export control purposes.

Q: Is the contact material difference between phosphor bronze and brass significant?

A: Both phosphor bronze (1-1761602-1 and 3-1761603-1) and brass (5103308-7 and AWHW 34G-0202-T) are acceptable contact materials for this connector category. Material selection does not affect electrical performance or mechanical compatibility for standard applications. Both materials provide equivalent conductivity and durability characteristics.
