Equivalent & Substitute Parts for H203PC

Part Overview

The H203PC is a pushbutton switch manufactured by Switchcraft Inc., classified as a Standard Panel Mount SPDT (Single Pole Double Throw) switch. This component is rated for 250mA DC at 28V with a circular 15.87mm diameter panel cutout and rear termination via PC pins. The H203PC is currently listed as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the H203PC is determined by strict equivalence across the following critical parameters:

• Circuit configuration (SPDT)
• Current rating (250mA DC minimum)
• Voltage rating (28V DC minimum)
• Mounting type (Panel Mount, Rear)
• Termination style (PC Pin)
• Panel cutout dimensions (Circular 15.87mm diameter)
• Actuator type (Round, Button)

The H203PCX meets all substitution criteria as a direct equivalent within the H-200PC series, with identical electrical ratings, mechanical interface, and form factor. The primary distinction is product status: H203PCX is active production, whereas H203PC is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The H203PCX is the direct functional equivalent for H203PC applications. Both components share identical electrical specifications (250mA DC, 28V), mechanical interface (Panel Mount, Rear with 15.87mm circular cutout), and circuit topology (SPDT).

Selection between these parts should be based on regulatory and compliance requirements. The H203PCX offers ROHS3 compliance, whereas the H203PC is non-compliant. For new designs or systems requiring RoHS certification, H203PCX is the appropriate selection. For legacy system maintenance where RoHS compliance is not mandated, either part provides equivalent electrical and mechanical performance.

Frequently Asked Questions (FAQ)

Q: Can H203PCX directly replace H203PC in existing assemblies? A: Yes. Both components are mechanically and electrically identical. The 15.87mm panel cutout, rear PC pin termination, and SPDT switching function are unchanged. No mechanical rework or circuit modification is required.

Q: What is the primary difference between H203PC and H203PCX? A: Product status and RoHS compliance. H203PC is obsolete and RoHS non-compliant. H203PCX is active production and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there any compatibility concerns with panel mounting? A: No. Both components use identical Panel Mount, Rear configuration with a circular 15.87mm diameter cutout. Existing panel apertures require no modification.

Q: Does the actuator color differ between these parts? A: No. Both H203PC and H203PCX feature black round button actuators with no marking.

Q: What termination method do these switches use? A: Both use PC Pin termination, suitable for direct insertion into printed circuit board holes or connector receptacles.
