Substitute Part Grouping Explanation

Substitution eligibility for the VC120642L800RP is determined by strict parametric equivalence in the following core electrical and mechanical specifications: varistor voltage range (minimum 45.9 V, typical 51 V, maximum 56.1 V), surge current capacity (180 A), maximum AC voltage rating (32 V), maximum DC voltage rating (42 V), energy absorption (0.8 J), circuit count (1), capacitance at 1 kHz (600 pF), operating temperature range (-55°C to 125°C), mounting type (Surface Mount), and package designation (MLCV 1206 / 3216 Metric).

The substitute parts VC120642L800DP and VCAS120642L800TP meet all required electrical parameters and mechanical compatibility criteria. Both maintain the same varistor voltage specifications, surge current rating, frequency-dependent capacitance, thermal operating range, and package footprint as the primary part. All three parts carry ROHS3 compliance and MSL 1 (Unlimited) ratings, ensuring consistency in environmental and regulatory requirements.

Engineering Selection Recommendations

All three parts—VC120642L800RP, VC120642L800DP, and VCAS120642L800TP—are active products with identical electrical and mechanical specifications, ensuring direct substitutability in circuit designs without performance degradation. Each part maintains full ROHS3 compliance and REACH Unaffected status, meeting standard environmental regulations.

The VCAS120642L800TP variant in the FLEXITERM® series carries AEC-Q200 automotive qualification, making it suitable for applications requiring automotive-grade component certification. Selection between the TransGuard® series (VC120642L800RP and VC120642L800DP) and the FLEXITERM® automotive variant depends on circuit application requirements and qualification standards applicable to the end system.

Frequently Asked Questions (FAQ)

Q: Can VC120642L800DP directly replace VC120642L800RP? A: Yes. Both parts share identical electrical parameters (51 V typical varistor voltage, 180 A surge current, 0.8 J energy), mechanical package specifications (MLCV 1206), and compliance ratings (ROHS3, MSL 1). The parts differ only in manufacturing batch designation and internal part family classification.

Q: What is the difference between TransGuard® and FLEXITERM® series parts? A: FLEXITERM® series variant (VCAS120642L800TP) includes AEC-Q200 automotive qualification. TransGuard® variants (VC120642L800RP and VC120642L800DP) are general-purpose industrial-grade parts. All maintain identical electrical and mechanical specifications. Selection depends on system qualification requirements.

Q: Are package dimensions identical across all three parts? A: Yes. All three parts use MLCV 1206 (3216 Metric) Surface Mount package with identical footprint, land pattern, and mounting requirements.

Q: Can these parts be used in automotive applications? A: The VCAS120642L800TP carries AEC-Q200 automotive qualification and is certified for automotive use. The VC120642L800RP and VC120642L800DP are not explicitly qualified to automotive standards based on provided specifications. Application suitability depends on specific automotive system requirements.

Q: What is the operating temperature range for all substitute parts? A: All three parts operate across -55°C to 125°C ambient temperature range, with rated performance across the full specification envelope.

Q: Are moisture sensitivity considerations different between the parts? A: No. All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions and indefinite shelf life under standard storage conditions.
