MTB-03 Equivalent & Substitute Parts

Part Overview

The MTB-03 is a 3-position rectangular connector housing manufactured by Adam Tech. This receptacle connector features a 0.156" (3.96mm) pitch and is designed for free-hanging, in-line applications with crimp termination and locking ramp fastening. The part is Active in product status and RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the original specification, enabling direct replacement in applications where the core functional requirements remain constant.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MTB-03 are identified based on strict equivalence of the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (3), pitch (0.156" / 3.96mm), number of rows (1), mounting type (free hanging, in-line), contact termination (crimp), and fastening type (locking ramp). All substitute parts listed maintain these core electrical and mechanical specifications, ensuring functional compatibility in applications designed for the MTB-03.

The substitute parts identified are:

• Molex 0009501031 (SPOX 5195 series)
• Molex 0430610003 (SPOX 43061 series)

Both parts satisfy the mandatory parameter alignment required for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

All three parts—MTB-03, 0009501031, and 0430610003—are Active products with ROHS3 compliance and MSL rating 1. Selection between these parts should be based on application-specific operating temperature requirements and insulation material compatibility.

The MTB-03 operates within -25°C to 85°C and uses Polyamide (PA66) insulation. The Molex 0009501031 extends the operating range to -40°C to 105°C with identical insulation material. The Molex 0430610003 operates within 0°C to 75°C with Polyester, Glass Filled insulation.

For applications requiring the widest temperature range, the 0009501031 is suitable. For applications within the 0°C to 75°C range where polyester insulation is acceptable, the 0430610003 is available. The MTB-03 remains the specified part for designs validated within its stated operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0009501031 directly replace the MTB-03?

A: Yes. Both parts share identical electrical and mechanical specifications: 3-position receptacle, 0.156" pitch, female socket contacts, crimp termination, and locking ramp fastening. The 0009501031 extends the operating temperature range to -40°C to 105°C compared to the MTB-03's -25°C to 85°C, making it suitable for wider temperature applications.

Q: What are the differences between the two Molex substitutes?

A: Both Molex parts maintain the core connector specifications. The primary differences are operating temperature range and insulation material. The 0009501031 operates -40°C to 105°C with Polyamide insulation, while the 0430610003 operates 0°C to 75°C with Polyester, Glass Filled insulation.

Q: Are all three parts RoHS3 compliant?

A: Yes. The MTB-03, 0009501031, and 0430610003 are all ROHS3 compliant with MSL rating 1 (Unlimited).

Q: Do these parts require specific contact pins?

A: All three housings are specified as "Contacts Not Included." Appropriate crimp contacts matching the 0.156" (3.96mm) pitch specification must be sourced separately.

Q: Which part should I select for my application?

A: Selection depends on your application's operating temperature range and insulation material requirements. If your design operates within -25°C to 85°C, the MTB-03 is the specified part. If extended temperature range is required, the 0009501031 is suitable. If operation is limited to 0°C to 75°C and polyester insulation is acceptable, the 0430610003 is available.
