Parameter Comparison

Engineering Selection Recommendations

For Direct Substitution (110-Position Requirement):

The TE Connectivity Z-PACK series parts (5100143-1 and 5106164-1) provide the closest electrical match to the HM2P40PDW145N9LF when a 110-position configuration is acceptable. Both maintain the 1.5 A current rating and support the full -55°C to 125°C operating range. Part 5106164-1 includes both alignment strip and board guide features, offering enhanced mechanical stability. Both parts are ROHS3 compliant and carry active product status with substantial inventory availability (3040 and 1516 units respectively).

For Reduced Current Applications:

The HARTING har-bus® HM series (17011102204 and 17011102402) are suitable for applications where current requirements do not exceed 1.0 A. Both parts maintain the 2.00mm pitch and press-fit termination, with board guide features included. These parts are ROHS3 compliant and active products. Voltage rating is not specified for these parts; applications requiring voltage ratings above 500 Vrms should not use these substitutes.

For Extended Position Count:

The Hirose Electric PCN21B-110PB-2PF-G provides 154 total positions (110 + 44 ground) with a ground plate feature. This part carries obsolete product status and should only be selected if existing inventory is available and no active alternatives meet application requirements. The voltage rating of 300 V is significantly lower than the main part; applications requiring higher voltage ratings should not use this substitute.

Compliance Considerations:

All substitute parts maintain MSL 1 rating and support the -55°C to 125°C operating temperature range. ROHS3 compliance is confirmed for TE Connectivity and HARTING parts. The main part and Hirose part carry RoHS Compliant status. REACH compliance status varies; TE Connectivity 5106164-1 is REACH Unaffected, while other parts show either REACH Affected or Vendor Undefined status.

Frequently Asked Questions (FAQ)

Q: Can the 110-position substitutes be used in place of the 132-position main part?

A: The 110-position substitutes (HARTING and TE Connectivity parts) are mechanically and electrically compatible with the same 2.00mm pitch and press-fit termination. However, they provide 22 fewer positions. Substitution is only valid if your application does not require the full 132-position capacity. The main part includes 22 dedicated ground positions; the 110-position alternatives do not include this ground plane configuration.

Q: What is the difference between the two HARTING parts (17011102204 and 17011102402)?

A: Both HARTING parts are 110-position headers with identical electrical specifications (1.0 A current rating, -55°C to 125°C operating range) and mechanical features (board guide, press-fit termination, 2.00mm pitch). The primary difference is packaging: 17011102204 is supplied in Tube packaging with 1042 units in stock, while 17011102402 is also in Tube packaging with 885 units in stock. Both are active products with ROHS3 compliance.

Q: How do the TE Connectivity parts differ from each other?

A: Both TE Connectivity Z-PACK parts (5100143-1 and 5106164-1) are 110-position headers with matching electrical ratings (1.5 A, 500 Vrms, -55°C to 125°C). The key difference is mechanical features: 5100143-1 includes a board guide, while 5106164-1 includes both an alignment strip and board guide. The alignment strip in 5106164-1 provides additional mechanical positioning precision. Part 5100143-1 has higher inventory availability (3040 units vs. 1516 units).

Q: Why is the Hirose part marked as obsolete?

A: The PCN21B-110PB-2PF-G is listed with obsolete product status, indicating it is no longer in active production. This part should only be selected if existing inventory is available and no active alternatives meet your application requirements. For new designs, active products from HARTING or TE Connectivity are recommended.

Q: What voltage rating should I use when selecting a substitute?

A: The main part HM2P40PDW145N9LF is rated for 750 Vrms. The TE Connectivity substitutes are rated for 500 Vrms, and the Hirose part is rated for 300 V. The HARTING parts do not specify a voltage rating. If your application requires voltage ratings above 500 Vrms, only the main part meets this specification. For applications operating at 500 Vrms or below, the TE Connectivity parts are suitable.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part and Hirose part carry RoHS Compliant status. The HARTING and TE Connectivity parts carry ROHS3 Compliant status, which represents an updated compliance standard. All parts meet RoHS requirements for new designs.

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

A: The TE Connectivity parts specify contact finish thickness at 30.0µin (0.76µm). The main part specifies flash thickness for gold finish. The HARTING parts do not specify thickness. Contact finish thickness affects durability and wear resistance in high-cycle mating applications. For applications with frequent connector mating cycles, the specified 30.0µin thickness of TE Connectivity parts provides documented durability characteristics.

Q: Can I use the 154-position Hirose part if I need more ground positions?

A: The PCN21B-110PB-2PF-G provides 154 total positions (110 + 44 ground) compared to the main part's 132 positions (110 + 22 ground). However, this part is obsolete and carries a lower voltage rating (300 V vs. 750 Vrms). Substitution should only occur if existing inventory is available and your application voltage requirements do not exceed 300 V. For new designs requiring additional ground positions, consult with manufacturers for active alternatives.
