Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HM2P66PD5115N9LLF is determined by the following critical parameters:

Position count and ground configuration, connector pitch (0.079" / 2.00mm), mounting method (through-hole), termination type (press-fit), current rating (1.5 A minimum), voltage rating (500Vrms minimum), and operating temperature range (-55°C ~ 125°C).

The identified substitute part 5352639-1 (TE Connectivity AMP Connectors, Z-PACK series) meets the core electrical and mechanical requirements with the following consideration: it provides 110 positions without dedicated ground pins, compared to the main part's 128 positions (110 + 18 ground). Both parts share identical pitch, mounting type, termination method, current rating, and operating temperature range. The substitute operates at 500Vrms versus the main part's 750Vrms, representing a reduced voltage capability.

Parameter Comparison

Engineering Selection Recommendations

Selection between the HM2P66PD5115N9LLF and 5352639-1 depends on application-specific requirements:

The HM2P66PD5115N9LLF is the primary choice for applications requiring 128 total positions with dedicated ground pins, 750Vrms voltage rating, and RoHS compliance. This part maintains active product status with established supply availability.

The 5352639-1 serves as a substitute for applications requiring 110 signal positions without dedicated ground configuration, where the 500Vrms voltage rating is acceptable, and ROHS3 compliance meets regulatory requirements. Both parts maintain identical current rating, pitch, mounting type, termination method, and operating temperature range. The substitute offers higher inventory availability at 1460 units.

Both parts carry EAR99 ECCN classification and HTSUS code 8536.69.4040, with MSL rating of 1 (Unlimited moisture sensitivity).

Frequently Asked Questions (FAQ)

Q: Can 5352639-1 directly replace HM2P66PD5115N9LLF in all applications?

A: Direct replacement is possible only when the application does not require the full 128-position capacity or dedicated ground pins. The substitute provides 110 positions and operates at 500Vrms versus 750Vrms. Verify that your circuit design accommodates these differences before substitution.

Q: What are the key electrical differences between these parts?

A: The primary electrical difference is voltage rating: HM2P66PD5115N9LLF operates at 750Vrms while 5352639-1 operates at 500Vrms. Current rating (1.5 A) and operating temperature range (-55°C ~ 125°C) are identical. Position count differs: 128 versus 110.

Q: Are both parts RoHS compliant?

A: Yes. HM2P66PD5115N9LLF is RoHS Compliant, and 5352639-1 is ROHS3 Compliant. Both meet RoHS requirements for lead-free construction.

Q: How do the packaging formats differ?

A: HM2P66PD5115N9LLF is supplied in Tray packaging, while 5352639-1 is supplied in Tube packaging. Packaging format may affect handling, storage, and integration into assembly processes.

Q: What is the significance of the connector style designation (AB 22 vs. B 22)?

A: Connector style designates the physical configuration and keying arrangement. AB 22 and B 22 represent different mechanical designs within their respective series. These differences affect physical fit and mating characteristics.

Q: Can these parts be used interchangeably in PCB designs?

A: Interchangeability requires verification of footprint compatibility, position count requirements, and voltage rating adequacy for your specific application. Consult mechanical drawings and electrical schematics to confirm compatibility before design substitution.
