Switchcraft H103PC Pushbutton Switch SPDT - Equivalent & Substitute Parts

Part Overview

The Switchcraft H103PC is a pushbutton switch with SPDT (Single Pole Double Throw) circuit configuration, rated for 250mA DC at 28V. This component features a round button actuator with red cap, panel mount rear termination using PC pins, and a circular 15.87mm diameter panel cutout. The H103PC is classified as obsolete, making identification of active equivalent parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution of the H103PC is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPDT topology must be maintained
• Electrical Ratings: Current rating of 250mA DC and voltage rating of 28V DC must be met or exceeded
• Mechanical Interface: Panel mount rear configuration with PC pin termination and 15.87mm circular cutout dimension
• Actuator Specification: Round button actuator with red cap coloring
• Series Compatibility: H-100PC series designation

The H103PCX qualifies as a direct substitute based on identical electrical specifications, mechanical dimensions, and functional characteristics within the same manufacturer series.

Parameter Comparison

Engineering Selection Recommendations

The H103PCX is a direct functional and mechanical equivalent to the H103PC. All electrical parameters, mechanical dimensions, and interface specifications are identical. The primary distinction is product lifecycle status: the H103PC is obsolete while the H103PCX is active in production.

The H103PCX additionally meets ROHS3 compliance requirements, whereas the H103PC is non-compliant. For new designs or systems requiring regulatory compliance documentation, the H103PCX is the appropriate selection. For legacy system maintenance where existing inventory of H103PC units is available, direct substitution with H103PCX is electrically and mechanically valid.

Frequently Asked Questions (FAQ)

Q: Can the H103PCX be used as a direct replacement for the H103PC in existing assemblies?

A: Yes. The H103PCX is mechanically and electrically identical to the H103PC. Panel cutout dimensions, PC pin termination, electrical ratings, and actuator specifications are equivalent. No circuit modifications or mechanical rework is required.

Q: What is the primary reason to substitute the H103PC with the H103PCX?

A: The H103PC is obsolete. The H103PCX is the active production equivalent within the same H-100PC series, ensuring continued availability and supply chain reliability.

Q: Does the H103PCX meet modern compliance standards?

A: Yes. The H103PCX is ROHS3 compliant, whereas the H103PC is non-compliant. For applications requiring regulatory compliance documentation, the H103PCX is the appropriate choice.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are rated for 250mA DC at 28V with SPDT circuit configuration. Electrical performance is identical.

Q: What are the critical dimensions for panel mounting?

A: Both parts require a circular panel cutout of 15.87mm diameter for rear panel mount installation with PC pin termination.
