Substitute Part Grouping Explanation

Substitution for the 88873-609LF is determined by strict equivalence in the following electrical and mechanical parameters:

Connector type (Header)
Contact type (Male Pin)
Number of positions (10) and rows (2)
Mating pitch (0.100" / 2.54mm)
Row spacing (0.100" / 2.54mm)
Mounting method (Through Hole)
Termination method (Solder)
Shrouding configuration (Shrouded - 4 Wall)
Contact shape (Square)
Flammability rating (UL94 V-0)
MSL rating (1 - Unlimited)

Substitute parts must maintain compatibility across these core parameters. Variations in contact finish, insulation material, fastening type, and operating temperature range are permitted where the primary electrical and mechanical interface remains unchanged.

Engineering Selection Recommendations

All listed substitute parts maintain electrical and mechanical compatibility with the 88873-609LF across the core interface parameters. Selection should be based on product status and regulatory compliance requirements.

Primary Recommendation: 52601-S10-4LF (Amphenol ICC) offers direct compatibility as an active product from the original manufacturer with RoHS compliance and identical mating pitch and position configuration.

Alternative Recommendations: HARTING SEK series parts (09185106324, 09185107324, 09195106324, 09195107324) provide active product status with ROHS3 compliance and extended operating temperature range (-55°C to 125°C). These parts feature keying slot functionality and are available in multiple packaging options.

Secondary Option: 1761681-3 (TE Connectivity AMP-Latch) is an active product with ROHS3 compliance, offering push-pull fastening consistent with the original part and specified electrical ratings (1A per contact, 250VAC).

The 09195107904 variant includes mounting flange and pick-and-place features with extended insulation height (0.681"), suitable for applications requiring additional mechanical support.

Frequently Asked Questions (FAQ)

Q: Can 52601-S10-4LF directly replace 88873-609LF in existing designs?

A: Yes. Both parts share identical mating pitch (0.100" / 2.54mm), position count (10), row configuration (2), mounting method (through hole), and termination (solder). The primary difference is product status: 52601-S10-4LF is active while 88873-609LF is obsolete.

Q: What are the key differences between Amphenol ICC and HARTING substitute options?

A: Amphenol ICC 52601-S10-4LF maintains the original contact length specifications (0.230" mating, 0.120" post). HARTING SEK series parts feature slightly longer mating contacts (0.240") and variable post lengths (0.114" or 0.177"). All maintain the same 2.54mm pitch and 10-position, 2-row configuration. HARTING parts include keying slot functionality and specify operating temperature range (-55°C to 125°C).

Q: Are there packaging differences between substitute parts?

A: Yes. 52601-S10-4LF is supplied in Tray packaging. HARTING parts are available in Tray or Bulk packaging. 1761681-3 is supplied in Bulk. Packaging selection does not affect electrical or mechanical interface compatibility.

Q: Which substitute part has the widest operating temperature range?

A: HARTING SEK series parts and 1761681-3 specify -55°C to 125°C operating range. The original 88873-609LF does not specify operating temperature. 1761681-3 specifies -65°C to 105°C, providing lower temperature capability.

Q: Do all substitute parts meet RoHS compliance?

A: 52601-S10-4LF is RoHS Compliant. All HARTING parts are ROHS3 Compliant. 1761681-3 is ROHS3 Compliant. The original 88873-609LF does not specify RoHS status.

Q: What is the significance of the keying slot feature in HARTING and TE Connectivity parts?

A: The keying slot provides polarization to prevent incorrect mating orientation. This is a functional enhancement not present in the original 88873-609LF but does not affect mechanical or electrical interface compatibility with standard mating connectors.

Q: Can parts with different contact post lengths be used interchangeably?

A: Contact post length affects PCB insertion depth and solder joint formation. Parts with 0.114" post length (HARTING 09185106324, 09185107324, 09195106324, 09195107324, 09195107904, and 1761681-3) differ from the original 0.120" specification. Parts with 0.177" post length (HARTING 09185106322, 09185107322, 09195105324740) provide deeper insertion. Selection should account for PCB thickness and solder joint requirements in the target application.
