HTMS-115-02-S-D Equivalent & Substitute Parts

Part Overview

The HTMS-115-02-S-D is a rectangular connector header manufactured by Samtec Inc., designed for through-hole board-to-board applications. This 30-position, 2-row connector operates at 0.050" (1.27mm) pitch and supports 5A per contact with an operating temperature range of -55°C to 125°C. The part is currently active in production with 815 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling component interchangeability in applications where the primary part is unavailable or procurement constraints exist.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTMS-115-02-S-D is determined by strict alignment of the following critical parameters:

• Connector type (Header)
• Contact type (Male Pin)
• Pitch - mating (0.050" / 1.27mm)
• Number of positions (30)
• Number of rows (2)
• Row spacing - mating (0.100" / 2.54mm)
• Mounting type (Through Hole)
• Termination method (Solder)
• Contact finish - mating (Gold)
• Shrouding configuration (Unshrouded)

The substitute part 5-103916-9 (TE Connectivity AMP Connectors) meets all critical electrical and mechanical parameters required for functional equivalence. Both parts share identical pitch, position count, row configuration, and mounting characteristics. Variations in contact length, insulation material composition, and operating temperature range do not preclude substitution when the application requirements fall within the overlapping specification envelope.

Parameter Comparison

Engineering Selection Recommendations

Both the HTMS-115-02-S-D and 5-103916-9 are active production parts with ROHS3 compliance and UL94 V-0 flammability ratings. Selection between these parts should be based on application-specific operating conditions:

The HTMS-115-02-S-D supports an extended upper operating temperature of 125°C compared to the 5-103916-9 maximum of 105°C. Applications requiring sustained operation above 105°C necessitate the Samtec part.

The 5-103916-9 supports operation at -65°C, providing 10°C lower temperature capability than the HTMS-115-02-S-D at -55°C. Applications requiring extended low-temperature performance favor the TE Connectivity part.

Both parts carry identical moisture sensitivity level (MSL 1), export classification (EAR99), and tariff codes (8536.69.4040), ensuring equivalent supply chain and regulatory handling.

Frequently Asked Questions (FAQ)

Q: Can the 5-103916-9 directly replace the HTMS-115-02-S-D in existing designs?

A: Direct mechanical and electrical substitution is supported when application operating temperatures remain within the overlapping range of -55°C to 105°C. PCB layout compatibility is ensured by identical pitch (0.050"), position count (30), row configuration (2 rows), and row spacing (0.100"). Minor variations in contact length and insulation material do not affect mating interface geometry.

Q: What are the key differences between these two connector headers?

A: The primary differences are insulation material (LCP versus Thermoplastic), contact material (Phosphor Bronze versus Copper Alloy), and operating temperature envelope. The HTMS-115-02-S-D extends to 125°C maximum; the 5-103916-9 extends to -65°C minimum. Contact length specifications differ slightly (0.100" mating versus 0.125" mating), resulting in a 0.013" overall length variation.

Q: Are both parts suitable for high-reliability applications?

A: Both parts meet UL94 V-0 flammability requirements and ROHS3 compliance. Both carry MSL 1 (unlimited moisture sensitivity), indicating no special storage or handling requirements. Selection should be based on specific application temperature and voltage requirements.

Q: What is the impact of different insulation materials on performance?

A: Liquid Crystal Polymer (LCP) in the HTMS-115-02-S-D and Thermoplastic in the 5-103916-9 both provide adequate electrical insulation and mechanical support for this connector class. Material selection does not affect electrical performance within the specified operating parameters but may influence thermal stability at temperature extremes.

Q: Can I use the 5-103916-9 in applications requiring 5A per contact current?

A: The 5-103916-9 current rating is not specified in the provided data. Confirmation of current-carrying capability with TE Connectivity technical documentation is necessary before substitution in applications requiring 5A per contact.
