TCR22-6RP Equivalent & Substitute Parts

Part Overview

The TCR22-6RP is a sensitive gate silicon controlled rectifier (SCR) manufactured by Littelfuse Inc., rated for 400V off-state voltage with 1.5A RMS on-state current capability in a TO-92 through-hole package. This component is classified as Active product status and is ROHS3 compliant. Substitute parts are necessary when the original manufacturer part becomes unavailable, when alternative packaging formats are required, or when sourcing from multiple suppliers is needed for supply chain resilience.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TCR22-6RP is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - Off State: 400 V
• Voltage - Gate Trigger (Vgt) Max: 800 mV
• SCR Type: Sensitive Gate
• Package / Case: TO-226-3, TO-92-3 (TO-226AA)
• Mounting Type: Through Hole
• RoHS Status: ROHS3 Compliant

Allowable Variation Parameters:

• Current - Gate Trigger (Igt) Max: May be lower than 200 µA
• Voltage - On State (Vtm) Max: May be higher than 1.5 V
• Current - On State (It RMS) Max: May be lower than 1.5 A
• Operating Temperature: May be wider range than -40°C to 110°C
• Product Status: Active or Obsolete (with supply verification)

The substitute parts P0102DA 1AA3, P0102DA 2AL3, P0102DA 5AL3, P0109DA 5AL3, and P0118DA 5AL3 are all manufactured by STMicroelectronics and meet the mandatory matching parameters. These parts maintain the same 400V off-state voltage, 800mV gate trigger voltage, sensitive gate SCR type, and TO-92-3 package configuration.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain ROHS3 compliance and REACH unaffected status, consistent with the original TCR22-6RP specification. Selection among active substitute parts should prioritize product status and supply availability.

Primary Substitutes (Active Status): P0102DA 5AL3, P0102DA 2AL3, and P0102DA 1AA3 are all active products manufactured by STMicroelectronics. These parts are functionally equivalent within the allowable parameter variations. P0102DA 5AL3 offers the highest inventory availability at 35,300 pieces. P0102DA 2AL3 provides cut tape packaging with 10,100 pieces in stock. P0102DA 1AA3 is available in bulk packaging with 4,848 pieces in stock.

Secondary Substitute (Active Status): P0109DA 5AL3 is an active product with 3,567 pieces available in cut tape packaging and maintains all mandatory parameter specifications.

Obsolete Substitute (Obsolete Status): P0118DA 5AL3 carries obsolete product status with 2,400 pieces in stock. This part exhibits a lower gate trigger current specification (5 µA maximum versus 200 µA) and should only be selected when supply of active alternatives is exhausted and application requirements accommodate the lower gate trigger current characteristic.

Frequently Asked Questions (FAQ)

Q: Can P0102DA series parts directly replace the TCR22-6RP in existing designs?

A: Yes, P0102DA 1AA3, P0102DA 2AL3, and P0102DA 5AL3 are direct functional equivalents. All three maintain the same 400V off-state voltage, 800mV gate trigger voltage, sensitive gate SCR type, and TO-92-3 package configuration. The primary differences are packaging format (bulk versus cut tape) and inventory availability.

Q: What is the significance of the lower on-state current rating in substitute parts?

A: The substitute parts are rated for 800mA RMS on-state current compared to the TCR22-6RP's 1.5A RMS rating. This represents a lower current capacity. Applications requiring the full 1.5A RMS capability must verify that substitute parts can accommodate the actual circuit current demands.

Q: Why does P0118DA 5AL3 have a different gate trigger current specification?

A: P0118DA 5AL3 specifies a maximum gate trigger current of 5 µA compared to 200 µA for other substitutes. This lower gate trigger current requirement may affect gate drive circuit design. Additionally, P0118DA 5AL3 carries obsolete product status, indicating discontinued manufacturing. Selection should prioritize active alternatives unless supply constraints necessitate obsolete part usage.

Q: Are there packaging differences between substitute options?

A: Yes. P0102DA 1AA3 is supplied in bulk packaging, while P0102DA 2AL3, P0102DA 5AL3, and P0109DA 5AL3 are supplied in cut tape packaging. All maintain identical TO-92-3 case configuration and through-hole mounting type. Packaging selection depends on assembly process requirements and order quantity.

Q: What is the operating temperature difference between the TCR22-6RP and substitutes?

A: The TCR22-6RP operates from -40°C to 110°C, while all substitute parts operate from -40°C to 125°C. The substitute parts provide a wider upper temperature operating range, which is compatible with applications designed for the original part's temperature specification.
