HT13CB103JN Equivalent & Substitute Parts

Part Overview

The HT13CB103JN is a 10000 pF ceramic capacitor rated at 100V with X7R temperature coefficient, manufactured by KEMET. This axial through-hole component is designed for general-purpose applications requiring high-temperature operation from -55°C to 200°C. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement continuity.

Key Parameters

Parameter	Value	Significance for Substitution
Capacitance	10000 pF	Critical - must match exactly
Voltage Rating	100V	Critical - must meet or exceed
Tolerance	±5%	Critical - determines circuit accuracy
Temperature Coefficient	X7R	Critical - defines capacitance stability across temperature range
Mounting Type	Through Hole Axial	Critical - determines PCB compatibility
Operating Temperature Range	-55°C ~ 200°C	Application-dependent - high-temperature capability
Lead Style	Straight	Important - affects insertion and soldering

Substitute Part Grouping Explanation

Substitution eligibility for the HT13CB103JN is determined by strict equivalence across electrical and mechanical parameters:

Electrical Equivalence Requirements:

Capacitance value: 10000 pF (exact match)
Voltage rating: 100V minimum
Tolerance: ±5%
Temperature coefficient: X7R

Mechanical Equivalence Requirements:

Mounting type: Through-hole axial configuration
Lead style: Straight leads
Package case: Axial

Identified Substitute: The SA101C103JAR (KYOCERA AVX) meets all electrical equivalence criteria. Physical dimensions differ (0.100" Dia x 0.170" L versus 0.135" Dia x 0.260" L), which is acceptable for through-hole axial components as long as lead spacing and PCB hole patterns accommodate the substitute. The operating temperature range of the substitute (-55°C ~ 125°C) is narrower than the original part (-55°C ~ 200°C), which may limit suitability for applications requiring the full high-temperature capability of the HT13CB103JN.

Engineering Selection Recommendations

SA101C103JAR as Primary Substitute:

The SA101C103JAR is electrically and mechanically equivalent to the HT13CB103JN across all critical parameters: capacitance, voltage rating, tolerance, and temperature coefficient. The substitute is in active production status, ensuring long-term availability and supply chain stability compared to the obsolete HT13CB103JN.

Temperature Range Consideration:

The SA101C103JAR operates to 125°C maximum, compared to the HT13CB103JN's 200°C maximum. Applications requiring sustained operation above 125°C cannot use this substitute. For such applications, alternative high-temperature ceramic capacitors with extended temperature ratings must be evaluated.

Compliance and Packaging:

The SA101C103JAR carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements. Packaging is supplied as Tape & Reel (TR), suitable for automated assembly processes. Physical dimensions are smaller (0.100" Dia x 0.170" L), which may provide PCB layout advantages in space-constrained designs.

Procurement Recommendation:

For applications operating within -55°C to 125°C, the SA101C103JAR provides direct functional substitution with improved supply chain status and regulatory compliance. Verify PCB hole spacing and lead length requirements before implementation.

Frequently Asked Questions (FAQ)

Q: Can SA101C103JAR replace HT13CB103JN in all applications?

A: Electrical and mechanical substitution is valid for applications operating within -55°C to 125°C. Applications requiring operation above 125°C require alternative components with extended temperature ratings.

Q: What are the physical dimension differences between these parts?

A: HT13CB103JN measures 0.135" Dia x 0.260" L (3.43mm x 6.60mm). SA101C103JAR measures 0.100" Dia x 0.170" L (2.54mm x 4.32mm). The substitute is physically smaller. Verify PCB hole spacing and lead length compatibility before substitution.

Q: Is the SA101C103JAR RoHS compliant?

A: Yes, SA101C103JAR is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

Q: Why is the HT13CB103JN listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The SA101C103JAR, as an active production part, provides continuity for new designs and ongoing procurement needs.

Q: Are there differences in packaging between these parts?

A: HT13CB103JN packaging is not specified in available data. SA101C103JAR is supplied as Tape & Reel (TR), standard for automated assembly. Confirm packaging requirements for your manufacturing process.

Q: What is the tolerance specification, and does it affect circuit performance?

A: Both parts carry ±5% tolerance. This tolerance band determines the acceptable capacitance variation across the production range and should be verified against circuit design requirements for frequency-dependent or precision applications.

Q: Can I use SA101C103JAR in high-temperature applications above 125°C?

A: No. SA101C103JAR maximum operating temperature is 125°C. The original HT13CB103JN supports operation to 200°C. For applications requiring extended high-temperature operation, alternative capacitor series with higher temperature ratings must be selected.
