Substitute Part Grouping Explanation
Substitution of the HM2P07PKA2H5GF is constrained by the following critical parameters:
Position Count & Configuration: The main part contains 154 total positions (110 signal + 44 ground) across 5 signal rows plus 2 ground rows. All identified substitutes provide 110 positions across 5 rows, representing a reduction in ground plane density. This configuration change affects board layout and power distribution characteristics.
Electrical Ratings: The original part is rated for 1.5A at 750Vrms. Substitute parts from TE Connectivity maintain the 1.5A current rating but operate at 500Vrms maximum. HARTING substitutes are rated for 1A at unspecified voltage. These differences must be evaluated against application requirements.
Pitch & Connector Style: All substitutes maintain the 0.079" (2.00mm) pitch and A 22 connector style, ensuring mechanical compatibility with existing mating connectors and PCB footprints.
Termination & Mounting: All substitutes use press-fit termination with through-hole mounting, maintaining assembly process compatibility.
Contact Finish & Temperature Range: All substitutes provide gold-plated contacts and operate across the -55°C to 125°C temperature range.
Compliance Status: The original part is RoHS non-compliant and obsolete. All active substitutes are RoHS3 compliant, meeting current regulatory requirements.

Engineering Selection Recommendations
Primary Substitutes (TE Connectivity Z-PACK Series): Parts 5100143-1, 5106164-1, 5106413-1, 5188731-1, and 1-5188398-9 are all TE Connectivity AMP Connectors with ROHS3 compliance and active product status. These maintain the 1.5A current rating and 500Vrms voltage specification. Part 5100143-1 offers the highest inventory availability (3040 pcs) and represents the most readily available option. Part 5106164-1 includes an alignment strip feature in addition to the board guide.
Secondary Substitutes (TE Connectivity Z-PACK Variants): Parts 1-5100143-9 and 3-5100143-0 are functionally equivalent to the primary group with ROHS3 and RoHS compliance respectively. Part 3-5100143-0 carries RoHS (non-ROHS3) compliance status.
Alternative Substitutes (HARTING har-bus® HM Series): Parts 17011102402 and 17011104201 provide active alternatives with ROHS3 compliance. These parts operate at 1A current rating with unspecified voltage rating, representing a reduction in electrical capacity compared to the original 1.5A/750Vrms specification.
Voltage Rating Consideration: All TE Connectivity substitutes operate at 500Vrms, which is lower than the original 750Vrms rating. Applications requiring the full 750Vrms specification cannot use these substitutes without design modification.
Position Count Reduction: All substitutes provide 110 positions across 5 rows, compared to the original 154 positions (110 signal + 44 ground). Applications dependent on the extended ground plane configuration require board redesign.
Frequently Asked Questions (FAQ)
Q: Can HM2P07PKA2H5GF be directly replaced with a 110-position substitute?
A: Direct replacement requires verification that the application does not depend on the 44 additional ground positions in the original 154-position configuration. The 110-position substitutes maintain the same 0.079" pitch and connector style, but the reduced ground plane density may affect power distribution and signal integrity in high-current or high-frequency applications.
Q: What is the voltage rating difference between the original part and substitutes?
A: The HM2P07PKA2H5GF is rated for 750Vrms, while all TE Connectivity substitutes are rated for 500Vrms. HARTING substitutes do not specify a voltage rating. Applications operating above 500Vrms cannot use TE Connectivity substitutes. HARTING parts require voltage specification verification before selection.
Q: Are all substitutes RoHS compliant?
A: All listed substitutes are RoHS compliant. The original HM2P07PKA2H5GF is RoHS non-compliant. TE Connectivity parts carry either RoHS or ROHS3 compliance status. HARTING parts are ROHS3 compliant. Current regulatory requirements favor ROHS3-compliant parts.
Q: What is the difference between 5100143-1 and 3-5100143-0?
A: Both parts are 110-position TE Connectivity Z-PACK headers with identical electrical specifications (1.5A, 500Vrms). The primary difference is compliance status: 5100143-1 is ROHS3 compliant, while 3-5100143-0 is RoHS compliant (non-ROHS3). For new designs, 5100143-1 is preferred.
Q: Does 5106164-1 offer any functional advantage over other TE Connectivity substitutes?
A: Part 5106164-1 includes an alignment strip feature in addition to the board guide, providing enhanced mechanical alignment during assembly. All other TE Connectivity substitutes include only the board guide feature. The alignment strip may improve assembly yield in high-volume production.
Q: What is the current rating difference with HARTING substitutes?
A: HARTING parts 17011102402 and 17011104201 are rated for 1A, compared to 1.5A for TE Connectivity substitutes and the original part. Applications requiring sustained currents above 1A should use TE Connectivity alternatives.
Q: Can substitutes be used interchangeably in the same application?
A: Substitutes can be used interchangeably only if the application requirements fall within the electrical and mechanical specifications of all candidate parts. Voltage rating (500Vrms vs. 750Vrms), current rating (1A vs. 1.5A), and position count (110 vs. 154) must be evaluated against specific application demands.
