Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the FHP-21-02-TM-S is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Number of positions (21)
• Mating pitch (0.156" / 3.96mm)
• Contact type (Female Socket)
• Mounting type (Surface Mount)
• Termination method (Solder)
• Contact finish (Tin)
• Operating temperature range (-55°C ~ 105°C)
• Insulation material (Liquid Crystal Polymer)
• Contact material (Phosphor Bronze)
• Series designation (FHP-21)
• Compliance certifications (ROHS3, MSL 1)

The identified substitute part FHP-21-02-T-S maintains full equivalence across all specified parameters, differing only in fastening type designation within the part number nomenclature while preserving all functional and mechanical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both FHP-21-02-TM-S and FHP-21-02-T-S maintain Active product status with identical ROHS3 compliance and MSL 1 ratings. Selection between these parts is based on inventory availability and supply chain considerations. The FHP-21-02-T-S currently maintains higher inventory levels (1019 pcs vs. 943 pcs), providing improved availability for procurement planning. Both parts satisfy identical electrical, mechanical, and environmental specifications for board-to-board rectangular connector applications requiring 21-position, 0.156" pitch surface mount receptacles.

Frequently Asked Questions (FAQ)

Q: Are FHP-21-02-TM-S and FHP-21-02-T-S electrically interchangeable?

A: Yes. Both parts are electrically equivalent, featuring identical contact materials (Phosphor Bronze), contact finishes (Tin), and operating temperature ranges (-55°C ~ 105°C).

Q: What is the difference between these part numbers?

A: The part numbers differ in the fastening type designation within the nomenclature. Both parts feature Push-Pull fastening and are mechanically and functionally equivalent.

Q: Can these connectors be used in the same PCB layout?

A: Yes. Both connectors share identical mating pitch (0.156"), insulation height (0.368"), and surface mount termination, allowing direct substitution in board designs.

Q: Are there any compliance differences between the two parts?

A: No. Both parts are ROHS3 compliant with MSL 1 (Unlimited) ratings and identical ECCN and HTSUS classifications.

Q: Which part should be selected for new designs?

A: Either part is suitable for new designs. Selection may be based on current inventory availability or existing supply chain relationships with Samtec Inc.
