Substitute Part Grouping Explanation

Substitution eligibility for the HTMS-110-02-G-D is determined by the following critical parameters:

Pitch - Mating: 0.050" (1.27mm) — must match exactly for mechanical and electrical compatibility
Number of Positions: 20 — determines contact count and PCB footprint
Number of Rows: 2 — defines physical layout and spacing requirements
Row Spacing - Mating: 0.100" (2.54mm) — critical for connector alignment and mating
Connector Type: Header — specifies the functional role in board-to-board connections
Contact Type: Male Pin — determines mating interface requirements
Mounting Type: Through Hole — establishes PCB assembly method
Termination: Solder — defines connection method to PCB
Fastening Type: Push-Pull — specifies mechanical engagement mechanism

The substitute part 5-103916-2 (TE Connectivity AMP Connectors) meets all critical substitution criteria, sharing identical pitch, position count, row configuration, row spacing, connector type, contact type, mounting method, termination type, and fastening mechanism.

Engineering Selection Recommendations

Both the HTMS-110-02-G-D and 5-103916-2 are active products with ROHS3 compliance and UL94 V-0 flammability ratings, making them suitable for equivalent substitution in board-to-board connector applications. The parts share identical mechanical and electrical interface specifications across all critical parameters.

The HTMS-110-02-G-D offers a wider operating temperature range (-55°C to 125°C) and specified current rating of 5A per contact. The 5-103916-2 provides a specified voltage rating of 30VAC and extended low-temperature capability (-65°C). Selection between these parts should be based on application-specific temperature and electrical requirements, as well as inventory availability and sourcing preferences.

Frequently Asked Questions (FAQ)

Q: Can the 5-103916-2 be used as a direct replacement for the HTMS-110-02-G-D?

A: Yes. Both connectors share identical pitch (0.050"), position count (20), row configuration (2 rows), row spacing (0.100"), connector type (header), contact type (male pin), mounting method (through hole), termination (solder), and fastening mechanism (push-pull). They are mechanically and electrically compatible for board-to-board applications.

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

A: The primary differences are operating temperature range (HTMS-110-02-G-D: -55°C to 125°C versus 5-103916-2: -65°C to 105°C), current rating specification (5A per contact for HTMS-110-02-G-D versus unspecified for 5-103916-2), and voltage rating specification (unspecified for HTMS-110-02-G-D versus 30VAC for 5-103916-2). Contact material and insulation material also differ between manufacturers.

Q: Are both parts RoHS compliant?

A: Yes. Both the HTMS-110-02-G-D and 5-103916-2 are ROHS3 compliant and carry UL94 V-0 flammability ratings, meeting current environmental and safety standards.

Q: What determines whether a connector can substitute for the HTMS-110-02-G-D?

A: Substitution requires matching pitch (0.050"), position count (20), row count (2), row spacing (0.100"), connector type (header), contact type (male pin), mounting type (through hole), termination method (solder), and fastening type (push-pull). Variations in temperature range, current rating, or voltage rating do not prevent substitution if application requirements are met.

Q: Do these connectors require different PCB footprints?

A: No. Both connectors share identical pitch and row spacing specifications, resulting in the same PCB footprint and mounting hole pattern.
