IM05GR Telecom Relay DPDT 2A 9V Equivalent & Substitute Parts

Part Overview

The IM05GR is a surface mount telecom relay manufactured by TE Connectivity Potter & Brumfield Relays, classified within the IM and AXICOM series. This DPDT (2 Form C) relay operates at 9VDC coil voltage with a 2A contact rating and is designed for telecom switching applications. The component is actively produced and maintains hermetically sealed construction with gull wing termination for surface mount assembly.

Substitute parts become necessary when the primary IM05GR experiences supply constraints, extended lead times, or when design flexibility permits alternative manufacturers meeting equivalent electrical and mechanical specifications. All substitute parts listed maintain functional compatibility through matching core parameters including coil voltage, contact form, contact rating, coil current, and operating temperature range.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IM05GR is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Coil voltage: 9VDC
• Contact form: DPDT (2 Form C)
• Contact rating: 2 A
• Coil current: 15.5 mA
• Coil resistance: 579 Ohms
• Must operate voltage: 6.75 VDC
• Must release voltage: 0.9 VDC
• Operating temperature range: -40°C ~ 85°C
• Mounting type: Surface Mount
• Termination style: Gull Wing
• Coil type: Non Latching
• Relay type: Telecom
• RoHS compliance: ROHS3 Compliant

All three substitute parts (AGQ200A09, TQ2SA-9V, and TQ2SA-9V-Z) satisfy these mandatory parameters. Variations in switching voltage ratings, contact material composition, seal rating designation, operate/release time tolerances, and packaging format do not preclude substitution when the core electrical and mechanical specifications align.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts maintain active product status and ROHS3 compliance, establishing baseline qualification for direct substitution with the IM05GR. Selection among the substitute options depends on application-specific requirements and supply chain considerations:

AGQ200A09 (Panasonic Electric Works): This substitute provides functional equivalence with reduced switching voltage capability (125VAC/110VDC maximum versus 250VAC/220VDC on the IM05GR). Applications operating within the AGQ200A09 switching voltage envelope present no compatibility constraints. Tube packaging accommodates manual assembly workflows. Operate and release times extend to 4 ms compared to the IM05GR specification of 3 ms.

TQ2SA-9V (Panasonic Electric Works): This substitute maintains switching voltage compatibility with the IM05GR (125VAC/220VDC maximum). Tube packaging supports manual assembly processes. Operate and release times extend to 4 ms. Contact material composition differs through use of Silver Nickel rather than Palladium/Ruthenium.

TQ2SA-9V-Z (Panasonic Electric Works): This substitute is functionally identical to TQ2SA-9V with switching voltage compatibility (125VAC/220VDC maximum) and 4 ms operate/release times. Tape & Reel packaging accommodates high-volume automated assembly. This configuration offers the highest inventory availability at 3226 pieces.

All substitute parts are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8536.41.0020, matching the IM05GR regulatory classification.

Frequently Asked Questions (FAQ)

Q: Can AGQ200A09 replace IM05GR in all applications?

A: AGQ200A09 provides electrical and mechanical substitution for applications where switching voltage does not exceed 125VAC or 110VDC. Applications requiring the IM05GR's 250VAC or 220VDC switching capability require TQ2SA-9V or TQ2SA-9V-Z instead.

Q: What is the significance of the 1 ms difference in operate and release times between IM05GR and the Panasonic substitutes?

A: The IM05GR operates and releases in 3 ms, while AGQ200A09, TQ2SA-9V, and TQ2SA-9V-Z operate and release in 4 ms. This 1 ms difference is within typical telecom relay performance tolerances and does not affect functional compatibility in standard switching applications. Applications with timing-critical requirements must evaluate this parameter against circuit specifications.

Q: How do packaging differences affect substitution?

A: IM05GR is supplied in Cut Tape (CT) format. AGQ200A09 and TQ2SA-9V are supplied in Tube packaging, suitable for manual pick-and-place assembly. TQ2SA-9V-Z is supplied in Tape & Reel (TR) format, optimized for automated high-speed assembly. Packaging selection depends on manufacturing process capability and volume requirements, not electrical compatibility.

Q: Are contact material differences significant for substitution?

A: IM05GR uses Palladium, Ruthenium, and Gold contact materials. AGQ200A09 uses Silver Palladium and Gold. TQ2SA-9V and TQ2SA-9V-Z use Silver Nickel and Gold. These material compositions are functionally equivalent for 2A switching at 9VDC in telecom applications. Contact material selection reflects manufacturer design practice and does not preclude substitution.

Q: What is the difference between TQ2SA-9V and TQ2SA-9V-Z?

A: TQ2SA-9V and TQ2SA-9V-Z are electrically and mechanically identical. The primary difference is packaging: TQ2SA-9V is supplied in Tube format (1621 pieces available), while TQ2SA-9V-Z is supplied in Tape & Reel format (3226 pieces available). Both are manufactured by Panasonic Electric Works within the TQ-SMD series.

Q: Does the absence of seal rating specification on Panasonic substitutes affect compatibility?

A: IM05GR specifies Sealed - Hermetically construction. AGQ200A09, TQ2SA-9V, and TQ2SA-9V-Z do not provide seal rating specification in available documentation. Applications requiring hermetically sealed construction must confirm seal specifications with Panasonic technical documentation before substitution.

Q: Can these substitutes be used interchangeably in existing designs?

A: Yes, all three substitutes are pin-compatible and functionally equivalent to IM05GR for applications within the specified electrical and switching voltage parameters. PCB layout and assembly processes require no modification. Substitution is direct at the component level.
