P6KE600C-B Equivalent & Substitute Parts

Part Overview

The P6KE600C-B is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., designed for telecom applications. This bidirectional zener diode operates with a reverse standoff voltage of 512V and provides clamping protection at 828V maximum. The device is housed in a DO-204AC (DO-15) axial through-hole package and delivers 600W peak pulse power with 750mA peak pulse current.

The P6KE600C-B carries an obsolete product status. Identifying equivalent substitute parts ensures design continuity and supply chain reliability for applications requiring identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the P6KE600C-B are determined by strict equivalence across all critical electrical and mechanical parameters. The following parameters establish substitution validity:

• Voltage - Reverse Standoff (Typ): 512V
• Voltage - Breakdown (Min): 570V
• Voltage - Clamping (Max) @ Ipp: 828V
• Current - Peak Pulse (10/1000µs): 750mA
• Power - Peak Pulse: 600W
• Operating Temperature Range: -55°C ~ 175°C (TJ)
• Package / Case: DO-204AC, DO-15, Axial
• Mounting Type: Through Hole
• Bidirectional Channels: 1

The P6KE600C-B obsolete status necessitates substitution with active product variants. Substitute parts P6KE600CA and P6KE600CA-B maintain identical electrical specifications and mechanical form factors, differing only in packaging configuration and product status.

Parameter Comparison

Engineering Selection Recommendations

Both P6KE600CA and P6KE600CA-B are direct electrical and mechanical equivalents to the obsolete P6KE600C-B. Selection between substitute options depends on procurement and inventory requirements:

P6KE600CA is supplied in Cut Tape (CT) packaging and carries Active product status with ROHS3 compliance. This variant supports automated assembly processes and offers the highest inventory availability at 3834 pieces.

P6KE600CA-B is supplied in Bulk packaging and carries Active product status with ROHS3 compliance. This variant accommodates manual assembly and reel-based handling with 998 pieces in stock.

Both substitutes maintain full electrical equivalence across voltage ratings, current specifications, power dissipation, and operating temperature ranges. Both achieve ROHS3 compliance, exceeding the RoHS Compliant status of the original part. Moisture sensitivity classification remains unchanged at MSL 1 (Unlimited).

Frequently Asked Questions (FAQ)

Q: Can P6KE600CA or P6KE600CA-B be used as direct replacements for P6KE600C-B?

A: Yes. Both substitute parts maintain identical electrical specifications including 512V reverse standoff voltage, 828V clamping voltage, 750mA peak pulse current, and 600W peak pulse power. Both use the same DO-204AC (DO-15) axial through-hole package and operate across the identical temperature range of -55°C to 175°C.

Q: What is the difference between P6KE600CA and P6KE600CA-B?

A: The primary difference is packaging configuration. P6KE600CA is supplied in Cut Tape (CT) format for automated pick-and-place assembly. P6KE600CA-B is supplied in Bulk format for manual assembly and reel handling. All electrical and mechanical specifications are identical.

Q: Why is the original P6KE600C-B marked as obsolete?

A: Product obsolescence indicates that Littelfuse Inc. has discontinued manufacturing this specific variant. The substitute parts P6KE600CA and P6KE600CA-B represent the current active product line with identical performance characteristics.

Q: Are there any compliance differences between the original and substitute parts?

A: The substitute parts carry ROHS3 compliance, which represents an enhanced regulatory standard compared to the RoHS Compliant status of the original P6KE600C-B. Both variants maintain MSL 1 (Unlimited) moisture sensitivity classification.

Q: Which substitute should be selected for new designs?

A: For new designs, either P6KE600CA or P6KE600CA-B is appropriate based on assembly methodology. P6KE600CA supports automated assembly with Cut Tape packaging. P6KE600CA-B supports manual assembly with Bulk packaging. Both are active products with full manufacturer support.

Q: Are the substitute parts suitable for telecom applications?

A: Yes. The substitute parts maintain all electrical specifications required for transient voltage suppression in telecom environments. The original P6KE600C-B was specified for telecom applications, and the substitutes provide identical performance characteristics.
