PCH-112D2,000 Equivalent & Substitute Parts

Part Overview

The PCH-112D2,000 is a general purpose relay manufactured by TE Connectivity Potter & Brumfield Relays. This through-hole mounted SPDT (Single Pole Double Throw) relay operates on a 12VDC coil and is rated for 5A switching capacity at maximum voltages of 277VAC or 30VDC. The part carries a Last Time Buy product status, indicating discontinued production with limited remaining inventory. Identification of equivalent and substitute parts is necessary to ensure design continuity and procurement availability for applications currently utilizing this relay.

Substitute Part Grouping Explanation

Substitution of the PCH-112D2,000 is determined by strict equivalence across the following critical parameters:

• Coil Voltage: 12VDC (exact match required)
• Contact Form: SPDT (1 Form C) configuration
• Contact Rating: 5A minimum current capacity
• Switching Voltage: 277VAC and 30VDC maximum ratings
• Mounting Type: Through Hole configuration
• Termination Style: PC Pin termination
• Coil Type: Non Latching operation
• Operating Temperature: -40°C to 85°C range
• Contact Material: Silver Tin Oxide (AgSnO)

The PCH-112D2000 (alternate part number format) meets all these parameters and qualifies as a parametric equivalent. Substitution is valid only when all listed parameters match the original specification.

Parameter Comparison

Engineering Selection Recommendations

The PCH-112D2000 is a direct parametric equivalent to the PCH-112D2,000 across all critical electrical and mechanical specifications. The primary distinction between these parts is product status: the main part (PCH-112D2,000) is designated Last Time Buy with higher inventory availability, while the substitute (PCH-112D2000) maintains Active status with lower stock levels.

From a compliance perspective, the main part carries RoHS3 compliance certification, while the substitute is RoHS non-compliant. For applications subject to RoHS requirements, the PCH-112D2,000 is the appropriate selection. The main part also provides defined REACH status, whereas the substitute requires vendor contact for REACH information.

Selection between these parts should prioritize compliance requirements and inventory availability for the specific application timeline. Both parts are functionally interchangeable based on electrical and mechanical parameters.

Frequently Asked Questions (FAQ)

Q: Can the PCH-112D2000 be used as a direct replacement for the PCH-112D2,000?

A: The PCH-112D2000 is electrically and mechanically equivalent to the PCH-112D2,000. Both parts share identical coil voltage (12VDC), contact form (SPDT), current rating (5A), switching voltage limits, mounting type (through hole), and termination style (PC pin). Substitution is valid from a functional standpoint. However, compliance certifications differ between the parts.

Q: What is the difference between these two part numbers?

A: The PCH-112D2,000 and PCH-112D2000 represent the same relay with different part number formatting conventions. The primary operational differences are product status (Last Time Buy versus Active) and compliance certifications (RoHS3 compliant versus non-compliant).

Q: Are there any compatibility concerns with PCB layout or footprint?

A: Both parts utilize identical through-hole PC pin termination and are mounted in the same configuration. No PCB layout modifications are required for substitution.

Q: Which part should be selected for new designs?

A: Selection depends on compliance requirements. For RoHS3-regulated applications, the PCH-112D2,000 is specified. For applications without RoHS requirements, either part is functionally suitable, though the PCH-112D2000 (Active status) may offer longer-term availability.

Q: What is the operating voltage range for these relays?

A: Both relays operate on a 12VDC coil with a must-operate voltage of 8.4VDC and must-release voltage of 0.6VDC. The contact switching capability extends to 277VAC or 30VDC maximum.

Q: Are these relays suitable for sealed or harsh environments?

A: Both parts carry a Sealed - Flux Protection rating, providing protection against flux contamination during manufacturing processes. Operating temperature range is -40°C to 85°C for both parts.
