Key Parameters

Substitute Part Grouping Explanation

The substitute parts are grouped based on matching critical electrical and mechanical parameters that define the interchangeability within the terminal blocks category. These key parameters include terminal block type, number of circuits, pitch, row count, current and voltage ratings, wire gauge compatibility, termination methods, barrier type, mounting type, material and finish of screw components, insulation material, RoHS compliance, and MSL rating. Substitution is justified only when these essential characteristics directly correspond between the main and alternative parts.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0387106902 terminal block holds a Last Time Buy status, whereas the Curtis Industries T38112-02-0 is active and available in inventory. Both models are ROHS3 compliant and have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating unrestricted use in standard assembly processes. The T38112-02-0 provides functional alignment with all critical electrical and mechanical parameters present in the original model.

Frequently Asked Questions (FAQ)

Q: What are the key criteria for substituting terminal blocks like Molex 0387106902?
A: Substitution requires alignment in barrier block type, number of circuits, pitch, wire gauge range, current and voltage ratings, termination style, mounting type, and regulatory compliance.

Q: Is the mounting style identical between Molex 0387106902 and Curtis Industries T38112-02-0?
A: Both models support through-hole mounting. The Curtis Industries part also supports chassis and panel mounting in addition.

Q: Will the current and voltage specifications be maintained with the substitute?
A: Yes, both parts have a voltage rating of 300V. The Curtis Industries T38112-02-0 supports up to 20A, which exceeds the 15A rating of the Molex part.

Q: Are there differences in wire gauge compatibility?
A: The Molex model supports 14-22 AWG, while the Curtis Industries model accommodates 12-22 AWG, covering and exceeding the original part's range.

Q: Is RoHS compliance maintained in the substitute part?
A: Yes, both Molex 0387106902 and Curtis Industries T38112-02-0 are ROHS3 compliant.

Q: Do both terminal blocks use the same insulation material?
A: The insulation material differs: Molex 0387106902 uses Polybutylene Terephthalate (PBT), while Curtis Industries T38112-02-0 uses Polypropylene (PP), as specified in the provided parameters.
