Switchcraft H103 Pushbutton Switch SPDT Equivalent & Substitute Parts

Part Overview

The Switchcraft H103 is a pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 250mA DC at 28V, featuring a red round button actuator and solder lug termination for panel mount rear installation. The H103 is classified as obsolete product status, making identification of active equivalent parts essential for ongoing system support and new procurement requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H103 is determined by strict equivalence across the following parameters: circuit configuration (SPDT), current rating (250mA DC), voltage rating (28V DC), mounting type (Panel Mount, Rear), actuator type (Round, Button), actuator color (Red), termination style (Solder Lug), and panel cutout dimensions (Circular - 15.87mm Dia). Parts meeting all these criteria within the H-100 series are classified as direct substitutes. The H103X qualifies as a direct substitute based on complete parameter alignment with the main part.

Parameter Comparison

Engineering Selection Recommendations

The H103X is the direct functional equivalent to the H103 and serves as the primary substitute for applications requiring the H103. The H103X maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. For new designs and ongoing procurement, the H103X is the specified replacement. Existing systems using the H103 may transition to the H103X without modification to electrical schematics or mechanical mounting interfaces.

Frequently Asked Questions (FAQ)

Q: Can the H103X be used as a direct replacement for the H103 in existing assemblies? A: Yes. The H103X is electrically and mechanically equivalent to the H103 across all specified parameters, including circuit configuration, current and voltage ratings, mounting type, actuator specifications, and panel cutout dimensions.

Q: What is the primary difference between the H103 and H103X? A: The H103X is an active product with ROHS3 compliance, while the H103 is obsolete and RoHS non-compliant. All functional and mechanical parameters are identical.

Q: Are there any compatibility concerns when substituting the H103X for the H103? A: No compatibility concerns exist. Both parts share identical termination style (Solder Lug), panel mount configuration (Rear), and panel cutout dimensions (Circular - 15.87mm Dia).

Q: What certifications apply to the H103X? A: The H103X carries ROHS3 compliance and REACH Unaffected status. Both parts share the same ECCN (EAR99) and HTSUS code (8536.50.9033).
