Engineering Selection Recommendations

HARTING SEK Series (09185645911, 09185645913, 09185646911, 09185646913, 09185647911, 09185647913, 09195646903)

These parts are active products with ROHS3 compliance and extended operating temperature range to 125°C. The SEK series provides superior compliance posture compared to the obsolete 3764-5202. Contact post length variations (0.114" or 0.177") accommodate different PCB thicknesses. The 09195646903 variant uses polycyclohexylenedimethylene terephthalate (PCT) insulation material instead of PBT.

TE Connectivity AMP-Latch Series (1-499141-2, 1-499786-2, 1-5499141-2)

These parts feature long-hook fastening and brass contact material. The 1-5499141-2 is the preferred selection within this series due to RoHS compliance. All three variants operate across -65°C to 105°C, providing extended low-temperature capability. Insulation height is 0.315" (8.00mm), which is 0.025" lower than the 3M original.

Compliance Considerations

For new designs or production requiring RoHS compliance, select HARTING SEK series or TE 1-5499141-2. For legacy system maintenance where RoHS compliance is not mandated, all listed substitutes provide functional equivalence.

Frequently Asked Questions (FAQ)

Q: Can HARTING SEK series parts directly replace the 3M 3764-5202 in existing designs?

A: Yes. All HARTING SEK variants maintain identical pitch (0.100"), position count (64), row configuration (2), and mounting type (through-hole, right-angle). Contact post length variations (0.114" or 0.177") are within acceptable tolerance for standard PCB applications. Insulation height difference of 0.009" is negligible for most mechanical constraints.

Q: What is the difference between HARTING parts with 0.114" and 0.177" post lengths?

A: Post length determines insertion depth into the mating connector. The 0.114" length (09185645913, 09185646913, 09185647913) is closer to the original 3M specification (0.112"). The 0.177" length (09185645911, 09185646911, 09185647911) provides deeper engagement for applications requiring maximum contact retention. Select based on mating connector specifications.

Q: Are TE AMP-Latch parts compatible with HARTING SEK mating connectors?

A: Both series maintain identical pitch and position count. However, TE parts feature long-hook fastening versus HARTING short-hook design, and insulation height differs by 0.020" (0.315" vs 0.335"). Mechanical compatibility depends on specific mating connector design. Consult connector documentation before cross-series substitution.

Q: Which substitute offers the best compliance profile?

A: HARTING SEK series and TE 1-5499141-2 are ROHS3 compliant. HARTING SEK additionally offers extended operating temperature to 125°C. For applications requiring maximum environmental margin, HARTING SEK series is preferred.

Q: Does insulation material affect electrical performance?

A: Both PBT and PCT insulation materials meet UL94 V-0 flammability requirements and provide equivalent electrical isolation. Material selection (PBT in most HARTING parts, PCT in 09195646903) does not affect functional compatibility. Selection is application-specific based on chemical resistance or thermal requirements.

Q: What packaging options are available?

A: HARTING SEK series is supplied in bulk packaging. TE 1-5499141-2 is supplied in trays. TE 1-499141-2 and 1-499786-2 are supplied in bulk. Packaging does not affect electrical or mechanical function.
