Key Parameters

Substitute Part Grouping Explanation

The SBH21-NBPN-D13-ST-BK from Sullins Connector Solutions qualifies as a substitute based on the following critical parameters:

• Identical connector type (Header) and contact type (Male Pin)
• Matching position count (26 positions) and row configuration (2 rows)
• Identical mating pitch (0.079" / 2.00mm) and row spacing (0.079" / 2.00mm)
• Equivalent shrouding design (Shrouded - 4 Wall)
• Matching mounting type (Through Hole) and termination method (Solder)
• Identical fastening type (Push-Pull) and contact shape (Square)
• Gold contact finish on mating surface
• RoHS3 compliance and MSL 1 rating

Substitution is valid where the specified parameters align with application requirements. Differences in contact material, insulation material, operating temperature range, and current rating must be evaluated against specific application constraints.

Parameter Comparison

Engineering Selection Recommendations

Both the STMM-113-02-G-D and SBH21-NBPN-D13-ST-BK are active production components with ROHS3 compliance and MSL 1 ratings, suitable for standard industrial applications.

The STMM-113-02-G-D features a wider operating temperature range (-55°C to 125°C) and higher current rating (3A), making it appropriate for extended temperature environments and higher-current applications. The Liquid Crystal Polymer insulation provides enhanced thermal and mechanical properties.

The SBH21-NBPN-D13-ST-BK operates within a narrower temperature range (-40°C to 105°C) with a 2A current rating. The Polyamide insulation material and Brass contact material represent alternative construction suitable for standard operating conditions. This part is available in tray packaging, which may align with specific procurement or assembly workflows.

Selection between these components should be based on application-specific requirements for operating temperature, current load, and packaging format.

Frequently Asked Questions (FAQ)

Q: Can the SBH21-NBPN-D13-ST-BK replace the STMM-113-02-G-D in all applications?

A: Substitution is valid where application requirements fall within the SBH21-NBPN-D13-ST-BK specifications. The lower operating temperature minimum (-40°C versus -55°C), reduced current rating (2A versus 3A), and different insulation material must be evaluated against specific application constraints.

Q: What are the key mechanical compatibility factors?

A: Both connectors share identical mating pitch (2.00mm), row spacing (2.00mm), position count (26), row configuration (2), shrouding design (4-wall), and contact shape (square). These parameters ensure mechanical interchangeability with mating connectors designed for either part.

Q: How do the contact materials differ?

A: The STMM-113-02-G-D uses Phosphor Bronze contacts, while the SBH21-NBPN-D13-ST-BK uses Brass contacts. Both materials are gold-plated on the mating surface. Contact material selection affects mechanical durability and electrical performance characteristics.

Q: What packaging differences exist?

A: The STMM-113-02-G-D is supplied in tube packaging, while the SBH21-NBPN-D13-ST-BK is supplied in tray packaging. Packaging format may influence handling, storage, and assembly line integration.

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

A: The STMM-113-02-G-D is rated to 125°C, suitable for extended high-temperature environments. The SBH21-NBPN-D13-ST-BK is rated to 105°C, appropriate for standard industrial temperature ranges. Application temperature requirements determine which part is suitable.
