Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SOLC-150-02-S-Q are qualified based on identical core electrical and mechanical parameters: 200 positions, 0.050" (1.27mm) mating pitch, 4-row configuration with 0.050" row spacing, surface mount solder termination, push-pull fastening, gold-plated forked contacts, and identical operating temperature range (-55°C ~ 125°C). All substitute parts maintain the same current rating (2.4A per Contact), insulation material (Liquid Crystal Polymer), contact material (Phosphor Bronze), and compliance certifications (ROHS3, UL94 V-0, MSL 1).

Substitutes differ only in optional mounting features: SOLC-150-02-S-Q-A includes a Board Guide feature, and SOLC-150-02-S-Q-LC includes a Board Lock feature. These features provide enhanced mechanical stability during mating but do not alter electrical performance or core dimensional compatibility.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SOLC-150-02-S-Q, SOLC-150-02-S-Q-A, and SOLC-150-02-S-Q-LC—are active production parts with identical electrical specifications, compliance certifications (ROHS3 Compliant, UL94 V-0), and moisture sensitivity ratings (MSL 1). Selection between these parts depends on mechanical mounting requirements:

SOLC-150-02-S-Q provides the base configuration without additional mounting features. SOLC-150-02-S-Q-A includes Board Guide functionality for enhanced alignment during mating. SOLC-150-02-S-Q-LC includes Board Lock functionality for positive mechanical retention. All three parts are electrically and thermally interchangeable within the specified operating range of -55°C to 125°C and support the full 2.4A per contact current rating.

Frequently Asked Questions (FAQ)

Q: Are SOLC-150-02-S-Q, SOLC-150-02-S-Q-A, and SOLC-150-02-S-Q-LC electrically interchangeable?

A: Yes. All three parts share identical electrical specifications including 200 positions, 0.050" (1.27mm) pitch, 2.4A per contact current rating, gold-plated contacts, and operating temperature range of -55°C to 125°C.

Q: What is the difference between the Board Guide and Board Lock features?

A: SOLC-150-02-S-Q-A includes a Board Guide feature for alignment assistance during connector mating. SOLC-150-02-S-Q-LC includes a Board Lock feature for positive mechanical retention after mating. The base SOLC-150-02-S-Q has neither feature.

Q: Can I substitute SOLC-150-02-S-Q-LC for SOLC-150-02-S-Q in an existing design?

A: Substitution is possible if the PCB layout accommodates the Board Lock feature. The core connector dimensions and electrical characteristics are identical, but the mechanical mounting features differ.

Q: Do all three parts meet the same compliance standards?

A: Yes. SOLC-150-02-S-Q, SOLC-150-02-S-Q-A, and SOLC-150-02-S-Q-LC are all ROHS3 Compliant, UL94 V-0 rated, and carry MSL 1 (Unlimited) moisture sensitivity level.

Q: Which part has the highest current inventory?

A: SOLC-150-02-S-Q-LC has 1061 units in stock, compared to 757 units for SOLC-150-02-S-Q-A and 654 units for SOLC-150-02-S-Q.
